Works a treat, great value!
I used a TravelKon esim for Japan in January and it worked a treat. I looked around out of curiosity at other options but TravelKon still provides the best value for money for whatI need. 20GB of data has been perfect for me, set up was quick and easy and worked as soon as we landed in Singapore. And it's worked perfectly across Malaysia & Indonesia. Highly recommended! Until our next overseas trip. ..

Top G Customer Service
With most purchases its all about the customer service, used this supplier twice and both times had an issue (my fault) and both times help chat line was able to assist and be patient with me and have me up and running. Highly recommended for this reason.

Great coverage
Great service all over North Vietnam. We toured to Hanoi, Ha Long Bay, Niħn Biħn and up in the Eco Nature Reserve of Pu Lõung not once did we run out of service
Set up was easy before departure and I just followed the I received in email after payment.
Will use Travelkon again.
